SMBus is a subset of the I C bus/protocol and was developed by Intel. 2 Implementations of the I C bus/protocol may require licenses from various entities, including Philips Electronics N.V. and North American Philips Corporation. Intel Active Management Technology requires the platform to have an Intel AMT-enabled chipset, network hardware and software, connection with a power source and a network connection. No computer system can provide absolute security under all conditions. Intel Trusted Execution Technology (Intel TXT) is a security technology under development by Intel and requires for operation a computer system with Intel Virtualization Technology, a Intel Trusted Execution Technology- enabled Intel processor, chipset, BIOS, Authenticated Code Modules, and an Intel or other Intel Trusted Execution Technology compatible measured virtual machine monitor. In addition, Intel Trusted Execution Technology requires the system to contain a TPMv1.2 as defined by the Trusted Computing Group and specific software for some uses. Intel Virtualization Technology requires a computer system with an enabled Intel processor, BIOS, virtual machine monitor (VMM) and, for some uses, certain computer system software enabled for it. Functionality, performance or other benefits will vary depending on hardware and software configurations and may require a BIOS update. Software applications may not be compatible with all operating systems. Please check with your application vendor.
